Abstract
The utility model relates to a noise-reduction mute box of a generator set. An air inlet box body is mounted on the inner side of a mute box body; air inlets are formed on the inner side of the mute box body, and communicated with the air inlet box body; an air outlet is formed at the top of the air inlet box body, and communicated with an engine; guide blades are arranged on one side, communicated with the air inlets, of the air inlet box body; one end of each guide blade is bent downwards; and bent angles are 25-60 degrees. According to the noise-reduction mute box, the waist-shaped air inlets allow more fresh air to enter the mute box body; circulation of the air is accelerated by a fan of the engine, so that heat generated by working of the engine is taken away, and the normal working of the engine is facilitated; the guide blades block dust sucked from the outside of the mute box body, and can reduce noise to the greater extent; and the air inlet box body supplies the fresh air to the engine directly by the air outlet, so that the sufficient burning of the engine is ensured, the power is higher, and the exhaust temperature is lower.
Description
Technical field
The utility model relates to generator unit structure, specifically is the quiet case of a kind of generator set noise reduction.
Background technique
Generator set fixedly has base plate on the chassis, motor and generator are fixed on the base plate, and motor and generator are provided with sealed cabinet outward, and the noise that produces during generator set work is enclosed in the sealed cabinet, but noise is still very big.Be provided with intake grill and exhaust outlet at sealed cabinet, utilize the fan on the motor to make the air ventilation in the sealed cabinet implement air-cooled.
The sealed cabinet that at present a lot of generator set manufacturers produce all is to adopt the fence type structure at intake grill, this structure air output is less, dust accumulates on the fence easily, hinders the air ventilation in the cabinet, and air temperature is higher in the cabinet, and the air inlet of motor is main from the air in the cabinet, therefore, cause the engine charge quantity not sufficient easily, it is insufficient to burn, power descends, adverse consequencess such as noise increase.
The model utility content
The purpose of this utility model is to provide a kind of generator set noise reduction quiet case at the defective of above-mentioned existing quiet case existence, solves the generator set noise greatly and the technical problem of engine charge deficiency, improves the power of generator set.
The utility model realizes that the technological scheme that above-mentioned purpose is taked is: the quiet case of a kind of generator set noise reduction, comprise quiet casing, the side of quiet casing is provided with intake grill, quiet casing has the air inlet casing in the installed inside that is provided with intake grill, and the air inlet casing is communicated with intake grill, and the top of air inlet casing is provided with exhaust outlet, exhaust outlet is communicated with motor, the air inlet casing is provided with guide vane being communicated with a side with intake grill, and an end of guide vane bends downwards, and the angle of bending is 25-60 °.
Described intake grill is waist type intake grill.
The utility model compared with prior art has following beneficial effect:
(1) in quiet casing, is installed into the gas tank body, the exhaust outlet at air inlet casing top is the suction port of motor, the air that enters the air inlet casing is fresh air, and be subjected to the interior temperatures involved of quiet casing less, directly fresh air is offered motor by exhaust outlet, guarantee that motor fully burns, more powerful, row's temperature is lower.
(2) bending angle being set in the air inlet casing is 25-60 ° of guide vane, the dust that quiet casing is sucked in outward blocks on the one hand, learn 25-60 ° guide vane of design simultaneously according to air stream, can reduce the noise that air flows and produces largely, and the noise that the work of quiet casing intrinsic motivation produces is isolated in the quiet casing and not to external radiation, reaches the purpose of quiet case noise reduction.
(3) intake grill is the import design of waist type, the ventilation section that is conducive to strengthen intake grill is long-pending, strengthen the circulation of air inflow, can make more fresh air enter quiet casing, accelerate the circulation of air by the fan of motor, the heat that engine operation produces is taken away, be conducive to the proper functioning of motor.
(4) the air inlet casing can be installed on the interior side plate of quiet casing, end face or the door as required, and quantity also can increase as required, with the circulation of accelerating air in the quiet casing and the air inflow that strengthens the motor fresh air.
Description of drawings
Fig. 1 is the structural representation of the quiet case of generator set noise reduction described in the utility model.
Fig. 2 is the waist type air inlet structure schematic representation of the quiet case of generator set noise reduction described in the utility model.
Embodiment
Below in conjunction with drawings and Examples the technical solution of the utility model is described further.
As depicted in figs. 1 and 2, the quiet case of a kind of generator set noise reduction, comprise quiet casing 1, the side of quiet casing 1 is provided with waist type intake grill 5, and quiet casing 1 has air inlet casing 2 in the installed inside that is provided with waist type intake grill 5, air inlet casing 2 is communicated with waist type intake grill 5, the top of air inlet casing 2 is provided with exhaust outlet 4, and exhaust outlet 4 is communicated with motor, and air inlet casing 2 is provided with guide vane 3 being communicated with a side with waist type intake grill 5, one end of guide vane 3 bends downwards, and the angle of bending is 25-60 °.
During work, it is long-pending that waist type intake grill 5 is conducive to strengthen the ventilation section of intake grill, strengthen the circulation of air inflow, can make more fresh air enter quiet casing 1, accelerate the circulation of air by the fan of motor, the heat that engine operation produces is taken away, be conducive to the proper functioning of motor.Guide vane 3 blocks the quiet casing 1 outer dust that sucks in, and can reduce the noise that air flows and produces largely, and the noise that quiet casing 1 intrinsic motivation work produces is isolated in the quiet casing 1 and not to external radiation, reaches the purpose of quiet case noise reduction.The exhaust outlet 4 at air inlet casing 2 tops is the suction port of motor, and the air that enters air inlet casing 2 is fresh air, and is subjected to the interior temperatures involved of quiet casing less, directly fresh air is offered motor by exhaust outlet 4, guarantee that motor fully burns, more powerful, row's temperature is lower.
Claims (2)
1. quiet case of generator set noise reduction, comprise quiet casing, the side of quiet casing is provided with intake grill, it is characterized in that, quiet casing has the air inlet casing in the installed inside that is provided with intake grill, the air inlet casing is communicated with intake grill, the top of air inlet casing is provided with exhaust outlet, and exhaust outlet is communicated with motor, and the air inlet casing is provided with guide vane being communicated with a side with intake grill, one end of guide vane bends downwards, and the angle of bending is 25-60 °.
2. the quiet case of generator set noise reduction according to claim 1 is characterized in that, described intake grill is waist type intake grill.
